Cross-Informant Agreement on the Child Behavior Checklist for Youths: A Meta-Analysis.

This meta-analysis of 169 studies examines the rank-order and mean-level agreements for the Child Behavior Checklist. The correlations between parents and teachers (.18-.35) and those between teachers and youths (.19-.32) were from small to moderate and generally moderate for those between parents and youths (.33-.40). The mean-level disagreements between parents and youths were small, while those between parents and teachers and those between teachers and youths varied. The rank-order agreement estimates were global, unlike those at mean level. The magnitude of mean-level disagreement was related to youth characteristics, parent characteristics, assessment contexts, and scale measured. Further research is needed on the agreement between teachers and youths, for which relatively few studies have been conducted.
